A cyano-bridged Mn2IIICrIII complex: Synthesis, structure and magnetic properties

A novel cyano-bridged Mn2IIICrIII complex {Cr(CN)4[CNMn(salen)(MeOH)]2}{[Mn(salen)(CH3OH)(H2O)]2}[Mn(salen)(MeOH)]2[Cr(CN)6] · 6CH3OH (1) (salen = N,N′-ethylene-bis-salicylideneaminato) has been synthesized and structurally characterized. X-ray structure analysis reveals that in 1, except for the trinuclear Mn2IIICrIII unit, there exist two mononuclear MnIII and one dimeric MnIII Schiff-base units. All these structural units are linked by hydrogen bond into a 3D network. The magnetic characterization shows that compound 1 displays a weak ferromagnetic behavior.
